以福建建阳市引种的邓恩桉为研究对象，以杉木和马尾松人工林为对照，通过调查分析其林分径级结构、高度结构、物种组成和林分各物种特征值，探讨福建北部高纬度地区引种邓恩桉对其林分结构的影响。结果表明，与其他几种林分相比，9年生邓恩桉平均胸径为12．1 cm，平均树高为11．9 m，生长速度明显快于杉木和马尾松；树种组成为19种，高于杉木的11 种和马尾松的10种；邓恩桉纯林中邓恩桉重要值为68．547％，在灌木层和草本层中重要值较大的为苦竹和芒萁。
以福建建暘市引種的鄧恩桉為研究對象，以杉木和馬尾鬆人工林為對照，通過調查分析其林分徑級結構、高度結構、物種組成和林分各物種特徵值，探討福建北部高緯度地區引種鄧恩桉對其林分結構的影響。結果錶明，與其他幾種林分相比，9年生鄧恩桉平均胸徑為12．1 cm，平均樹高為11．9 m，生長速度明顯快于杉木和馬尾鬆；樹種組成為19種，高于杉木的11 種和馬尾鬆的10種；鄧恩桉純林中鄧恩桉重要值為68．547％，在灌木層和草本層中重要值較大的為苦竹和芒萁。

The introduced Eucalyptus dunnii growing in northern high latitude areas of Jianyang in Fujian was taken as the research object while Cunninghamia lanceolata and Pinus massoniana used as comparison.A discus-sion was made for the effects on the tree plantation introduced in high altitude area based on the analysis of class structure,height structure,species composition.The result showed:comparing with other forest stand,the average DBH of 9-year-old Eucalyptus dunnii was 12.1 cm,and the average of height was 1 1. 9 cm.It is clear to see the growth of the species was faster than Cunninghamia lanceolate and Pinus massoniana.The species composition was 19 and higher than Cunninghamia lanceolate(1 1 )and Pinus massoniana(10).In Eucalyptus dunnii pure forest, the important value of Eucalyptus dunnii was 68. 547%.Meanwhile,in shrubs and herb layer Pleioblastus amarus and Dicranopteris pedata had greater important value than others.
